我想到的另一种可能性是，使用 grep ，is：

Another possibility I came up with, inspired by using grep, is:

tasklist /FI "IMAGENAME eq myapp.exe" 2>NUL | find /I /N "myapp.exe">NUL
if "%ERRORLEVEL%"=="0" echo Programm is running

它不需要保存一个额外的文件，所以我喜欢这种方法。

It doesn't need to save an extra file, so I prefer this method.
